Application filed October 18, I923. Serial No. 669,235.

To all whom it may concern:

Be it known that I, Mourns SABLE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented. new and useful Improvements in Adjustable Arch Supporters, of which the following is a specification.

This invention relates to a metallic foot arch supporter designed to be wornon the inside of a boot or shoe, for supporting the arch of the instep, especially in cases where the arch of the foot has fallen or broken down, to restore the same to normal condition.

An important object of the invention is to provide an arch supporter construction in which the arch supporting plates of the structure may be quickly adjusted longitudinally and vertically to conform'to foot arches of various conformations.

Other objects and advantages will be apparent from the following specification, and in the accompanying drawings I have illustrated a preferred embodiment of my in vention, it being understood however, that no limitation is necessarily made to the precise structural details exhibited therein, but various changes, alterations and modifications may be resorted towithin the scope of my invention when desired.

Fig. 1 is a side elevation of a. shoe with parts broken away showing the supporting arch in place therein. a

Fig. 2 isa bottom plan view of the arch supporter.

Fig. 3 is a side elevation of the same.

Fig. 4 is a partial side elevation of the arch supporter showing the adjustable arch supporting plates elevated to the maximum height.

Fig. 5 is a transverse section of the arch supporter taken on line 5-5 of Fig.2.

steel, consisting of two members 10 and 11 substantially triangular in form, and mounted on the arch side of the supporting member. The oppositely disposed edge portions 12 and 13 of the members 10 and 11 ofthe arch supporting bridge 9 overlap, edge portion 13 resting on edge portion 12, while the angular ends 14:, 15, of the members are each provided with a screw threaded aperture 16, 17, the ends contacting with the outer edge of the supporting plate 8 directly over elongated slots 18, 19, formed therein, countersunk screws 20, 21, passing through the slots and engaging the apertures in the supporting members, whereby the bridge may be adjusted longitudinally along the supporting plate.

The inner edge of each plate member 10 and 11 is provided with a lug or hook 22, 23, which pass through slots 24, 25, formed in the supporting plate and serve to hold the inneredgc of the plate in position and prevent a tilting action when the weight of a person is applied thereto. The ends of the hooks are bent over, passing through slots26, 27, formed parallel to the slots 24:, 25, so that accidental disengagement is obviated.

Pivotally mounted on base plate 8, approximately midway of its ends, and disposed under the arch supporting bridge member 9, is an elevating member 28, of wedge form, provided on its under face with a downwardly projecting pivotal pin 29 which'engages an aperture 30 formed in the base plate. The upper surface of the elevating member inclines upwardly from its pivotal end, and the upper surface at its free end is bevelled transversely as at 31 as bestshown in Fig. 3 of the drawing, to form a cam or'lift-ing surface when the member is swung on its pivot to elevate the bridge member. The outer free end of member 28 is provided on its under face with a screw threaded aperture 32, and is engaged by a positioning screw 33 which passes through; a segmental slot 34. formed in the supporting or base plate 8, the radial point of said slot being the pivotal point of the elevating or cam member 28.

When the bridge elevating member is in position on the base. or supporting plate 8, the outer longitudinally extending edges 35 of each member are of substantially the same configuration as the longitudinally extending curved edge 36 of the base or supporting plate, the wedge shaped elevating member 28 maintaining the side edges of the bridge a sutiicient distance above the flat base plate to lit the arch 01" a persons toot, the inner edges 37 contacting with the upper surface of the base member to form a smooth oven surface.

When a person whose arch has fallen desires to use the arch supporter, the set screws 20 and 21 are loosened suiiiciently so that the ends of the bridge supporting members 10 and 11 are at the ends of the slots adjacent each end ot the supporting plate 8, and the elevating member 28 is in the position as clearly shown in the Figs. 2 and 3 of the drawing. In this position, the bridge is in its lowest elevated position. As the persons foot becomes accustomed to the supporting arch, and the arch of the foot begins to resume its normal condition, the set screws 20 and 21 are loosened, as well as the positioning set screw the elevating member 28 being swung on its pivotal point slightly inwardly so as to cause an eleva tion of the bridge member 9, the elevating member acting as a wedge or cam. The various screws 20, 21, 33, are then tightened to hold the bridge member in its adjusted position. This operation may be repeated :troni time to time as the foot becomes accustomed to the arch supporter, and within a short time the elevating member may be swung to the inner end of the segmental slot formed in the base plate, the height of the supporting bridge coinciding with the normal height of the arch of the foot.

From the above description it will be noted that I have provided an arch supporter in which the bridge or arch supporting member may be adjusted longitudinally of the base plate on which it is mounted, and also, which is most important, the bridge may be elevated vertically from a minimum to a maximum height with little or no trouble.

hat I claim is:

1. An arch supporter, comprising a base plate, a bridge formed in two parts mounted thereon, the oppositely disposed ends of said bridge parts overlapping, and cam means secured to said base plate for adjusting said bridge vertically.

2. In an arch supporter a base plate, a two part arch supporting bridge mounted on said plate, each part of said bridge being adjustable longitudinally of said base plate, and. means for adjusting said bridge vertieally intermediate its ends.

in an arch supporter a base plate, a brirge formed in two parts mounted thereon, means to adjust the bridge parts longitudinally with respect to said base plate, and a wedge meml er pivotally secured to said base plate for adjusting said bridge vertically.

at. in an arch supporter, a metal base plate, a two part bridge member mounted on said plate, said bridge members being adjustable longitudinally along said base plate, means to maintain said l'nidge members against movement ai' er an adjustn'ient, a wedge member mounted on said plate and contacting with the under face of said bridge member tor adjusting the same vertically, and means to secure said wedge member against movement after an adjustment.

5. in an arch supporter, comprising a base resilient bridge member mounted on upper face of said base plate, a wedge 'ieml'zer pivotally secured to said base plate ror adjusting said bridge member vertically with respect to said base plate, and means to hold said wedge member in its adjusted position.

6. An arch supporter comprising a base plate, an arch supporting bridge mounted on said plate. the inner edge of said bri( ge being pivotally connected to said base plate, and means to adjust the free edge of said brio e vertically intermediate its ends.

7. An arch supporter comprising a base plate, a two part arch supporting bridge mounted on said plate, the inner edge of said bridge being hingedly secured to said base plate, the ends of said bridge being adjustably secured to the base plate and the free ends overlapping each other, and means to adjust the members of the bridge verti- Cally.

S. An arch supporter comprising a base plate, a two part arch supporting bridge adjustably secured at its ends to the base plate and a hinge for connecting the inner longi tudinal edge of each bridge part with said plate, the free ends of said brid 'e part overlapping, and cam shaped wedge member pivotally secured to the base plate adjacent the free ends of said bridge parts for adjusting the bridge vertically with respect to said base plate.

In witness that I claim the foregoing I have hereunto subscribed my name this 27th day of September, 1928.
